POD6 not actually supported

should be supported per here:

https://github.com/github/markup#markups

if you try to create a file readme.pod6 like this:

=head1 top level heading
 
=head2 second level heading 
 
=head3 third level heading 

you just get this output:

=head1 top level heading =head2 second level heading =head3 third level heading

Thanks for flagging this; I've removed it from the README. Support had to be withdrawn for security reasons -- Pod::To::HTML actually executes the perl6 program as part of generating its docs, which we can't allow.

We'll get a new rendering without execution, and we'll submit the PR again.
